This project involves the study of oscillating electrochemical systems, specifically the oscillations in electric current produced when arrays of nickel electrodes dissolve in sulfuric acid while held at a constant potential. Previous experiments have shown that nickel electrodes do exhibit oscillatory and chaotic behavior, but do not couple easily. This project will attempt to produce an array of electrodes much smaller and more closely-spaced than in previous experiments. In so doing, I hope to observe coupling between the electrodes’oscillations. This experiment may help us better understand nonlinear oscillators and coupling, which have biological applications in the study of circadian rhythms and epilepsy.
